BL8022
800mA 1.5MHz 7V Synchronous Buck Converter
DESCRIPTION
The BL8022 is a high-efficiency, DC-to-DC step-
down switching regulators, capable of delivering up
to 800mA of output current. The device operates
from an input voltage range of 2.6V to 7.0V and
provides an output voltage from 0.6V to VIN,
making the BL8022 ideal for low voltage power
conversions. Running at a fixed frequency of
1.5MHz allows the use of small external
components, such as ceramic input and output caps,
as well as small inductors, while still providing low
output ripples. This low noise output along with its
excellent efficiency achieved by the internal
synchronous rectifier, making BL8022 an ideal
green replacement for large power consuming
linear regulators. Internal soft-start control circuitry
reduces inrush current. Short-circuit and thermal-
overload protection improves design reliability.
BL8022 is housed in a SOT23-5 Package
